For the sake of ease, a quick instruction is given for readers to reproduce the whole process. Note that the programs are tested on Linux(Ubuntu release 16.04), Python 3.7 from Anaconda 4.5.11.

Install PyTorch (>0.4.0)

conda install pytorch -c pytorch

Get this repo

git clone https://github.com/yzhangee/AutoSF
cd AutoSF
tar -zvxf KG_Data.tar.gz 

Reproducing the searching/fine-tuning/evaluation procedure, please refer to the bash file "run.sh"

bash run.sh

Explaination of the searched SFs in the file "searched_SFs.txt":

• The first 4 values (a,b,c,d) represent h_1 * r_1 * t_a + h_2 * r_2 * t_b + h_3 * r_3 * t_c + h_4 * r_4 * t_d.

• For the others, every 4 values represent one adding block: index of r, index of h, index of t, the sign s.

You can also rely on the "evaluate.py" file to evaluate the searched SFs by manually setting the struct variable.
